Sarah Perez: "Facebook, despite anecdotal reports to the contrary, isn’t struggling to find traction with its youngest users. According to Pew Internet & American Life’s latest figures, 86 percent of Internet users 18 to 29 use Facebook today. The site is not in decline, and according to new data from J.P. Morgan analyst Doug Anmuth (via All Things D), Facebook is growing more than other mobile competitors like Twitter, Snapchat, WhatsApp and even its own property, Instagram."
